A new class of phytoalexins from grapevines


Novel phytoalexins which have been isolated from grapevine leaves are oligomeric forms of the trihydroxy stilbene resveratrol, which co-occurs with these compounds. The characterization of one of these phytoalexins as a resveratrol dimer, designated ε-viniferin, is described as well as a model for its biosynthesis from resveratrol.
